If you clicked on my first link it should download a file called "
837.mjp". If everything is configured right with your system MC should automatically open this file and then download and install the skin. You can also try to drag & drop the "
837.mjp" onto MC. Should also do the trick I guess.
If not: I recommend to reinstall MC!
Concerning your skin bug: looks as if it's font size related.
As you can see at my attached screenshot (same screen resolution as you use) you are obviously using another font size. Does it happen to all skins or just to Black and Blue?
If only Black and Blue: Try to reinstall the skin.
If all skins: have a look at your MC program options. Therefor open Tools -> Options. Type "select font" at the lower left. Select "Tree & View" at the upper left. Click "Select font..." on the right. Should be a size round about 9pt.
But: I'm not absolutely sure if this setting also effects the font size of the players display or only the font size of the library views. You'll see
